What is the average rate of change in profit from Hour 5 to Hour 10?
Answer:
d
Step-by-step explanation:
so at 5 hours he was at a profit of 900 and 5 hours later he is at a profit 1500 then you can sub tract 900 from 1500 which gives you 600
$600 is the average rate of change in profit from Hour 5 to Hour 10
What is Rate of change?A rate of change is a rate that describes how one quantity changes in relation to another quantity
The given table is
Hour Profit
0 $0
2.5 $500
5 $900
7.5 $1200
10 $1500
5 hours the profit is 900 and 5 hours later he is at a profit 1500
We need to subtract 900 from 1500 to find the average rate of change.
1500-900=600
Hence $600 is the average rate of change in profit from Hour 5 to Hour 10

Answer:
∠ EDF =104°
Step-by-step explanation:
The measure of the chord- chord angle EDF is half the sum of the of the arcs intercepted by the angle and its vertical angle, that is
∠ EDF = [tex]\frac{1}{2}[/tex] (arc EF + arc GU )
= [tex]\frac{1}{2}[/tex] (147 + 61)°
= [tex]\frac{1}{2}[/tex] × 208°
= 104°

Answer:
A, B and D
Step-by-step explanation:
The zeros of f(x) are the points located on the x- axis, that is where y = 0
We can check which ones are the solutions by finding the zeros of f(x)
To find the zeros let f(x) = 0 , that is
(x² + 2x - 8)(x - 6) = 0 ← factorise the quadratic
(x + 4)(x - 2)(x - 6) = 0
Equate each factor to zero and solve for x
x + 4 = 0 ⇒ x = - 4
x - 2 = 0 ⇒ x = 2
x - 6 = 0 ⇒ x = 6
There are 3 zeros at x = - 4, x = 2, x = 6
These are located at A, B and D
Answer:
A, D, B
Step-by-step explanation:
The roots (zeroes) are the x values where the graph intersects the x-axis. To find the roots(zeroes), replace y with 0 and solve for x.

There are several bowls containing various amounts of grapes on a table. When 12 of the bowls each had 8 more grapes added to them, the mean (average) number of grapes per bowl increased by 6. How many bowls of grapes are on the table?
Answer:
There are 16 bowls
Step-by-step explanation:
Number of bowls = x
Total grapes added = 12 x 8 = 96
The average increased by 6
So 96/6 = 16
There were 16 bowls of grapes on the table
OR
12 x 8 = 96
96/6=16
Answer:
16 bowls
Step-by-step explanation:
Number of bowls = x
Total grapes added = 12 x 8 = 96
The average increased by 6
So 96/6 = 16
There were 16 bowls of grapes on the table

They are similar triangles as all 3 angles are same
Answer:
C. The triangles are similar
Step-by-step explanation:
Similar means same figure/shape but not the same size, congruent is exactly the same. We can see that the two triangles are similar in shape, and if u want to go that fat, they have the same angles too. But they're not the same size so they are similar.

Earl runs 60 meters in 40 seconds. How many meters does Earl run per second?
Earl runs ___ meters per second.
Answer:
Earl runs 1.5 meters per second
Step-by-step explanation: 60 divided by 40= 1.5
Answer:
1.5 meters/s
Step-by-step explanation:
Since he runs 60 meters in 40 seconds, we can divide 60 by 40 to get how quickly he runs in meters/s. 60/40 = 6/4 = 3/2 = 1.5, so Earl runs 1.5 meters per second.

Determine whether the relationship between the two quantities described in each table is linear.
If so, find the constant rate of change. If not, explain your reasoning.
O Yes; 4 apples/tree
O Yes; 20 apples/tree
O No; No constant rate of change
O None of the above
Answer:
No; No constant rate of change
Step-by-step explanation:
5 trees > 100 apples --> 20 apples/tree
10 trees > 120 apples --> 12 apples/tree
15 trees > 150 apples --> 10 apples/tree
20 trees > 180 apples --> 6 apples/tree
Find the constant of proportionality for the table and write in the form y = kx.
A) y = 1/6x
B) y = 6x
C) y = 7x
D) y = 42x
Answer:
The constant of proportionality for the table will be: k=6
Thus, the equation becomes
[tex]y=kx[/tex]
[tex]y=6x[/tex]Step-by-step explanation:
The constant of proportionality, k, is the constant value of the ratio of two proportional quantities y and x.
We know the equation
[tex]y=kx[/tex]
where k is the constant of proportionality.
Looking at the graph,
at x=7, the value of y=42
so the ratio of y/x = 42/7 = 6
at x=14, the value of y=84
so the ratio of y/x = 84/14 = 6
at x=21, the value of y=126
so the ratio of y/x = 126/21 = 6
at x=28, the value of y=168
so the ratio of y/x = 168/28 = 6
We observe that the ratio of y/x remains constant which y/x=6
so using the equation
[tex]y=kx[/tex]
take any point let say (7, 42)
42 = k(7)
42/7=k
6 = k
Therefore, the constant of proportionality for the table will be: k=6
Thus, the equation becomes
[tex]y=kx[/tex]
[tex]y=6x[/tex]

Si en un triángulo un ángulo mide 30º y otro 70º¿cuánto mide el tercer ángulo?
Answer:
El tercer ángulo es 80
Step-by-step explanation:
En un triángulo hay 3 ángulos. Cuando sumas todos los ángulos, es igual a 180. Entonces, para esto, todo lo que tienes que hacer es sumar 30 y 70, lo que te da 100. Luego, restar 100 de 180, lo que te da 80. Lo que significa que el tercer ángulo es 80 :)
The sum of two numbers is 116 and their difference is 18. Find the larger number.
aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
Answer:
67
Step-by-step explanation:
let larger number be x and the other be y.
x - y = 18
x = 18+y
now, x + y = 116
therefore, 18+y+y= 116
18 + 2y =116
2y = 116-18
2y = 98
y = 98/2 = 49
larger number = 49 + 18 = 67

Answer: 3
Step-by-step explanation:
I just finished the test and this was the answer I put and it was right.
9x+6y=b
6y=b-9x
y=b/6 -9/6x
y=b/6-3x/2
y= -3x/2 +b/6
3x + 2y = 1
2y = 1 - 3x
y = 1/2 -3/2x
y = -3/2x + 1/2
b/6=1/2
b=3
